I don't think there'll be an iPhone 9. Apple jumped to 10 in order to compete with Samsung. Sure, they're 2 different devices but you have to admit that the number 10 sounds more appealing than 8. It's all marketing. I imagine next gen to be called X1 and so on...
I like this. Two separate lines. The numbers continue for the "old model" that started in 2007. X line for the tenth anniversary reboot. X2 makes more sense for 2018 though. This year is technically X1. We're supposed to think of it as iphone 10. But everyone I've met including me calls it iphone "X" like the letter. OSX too come to think of it.
X2 and X2 plus for next year. Maybe an iPhone 9 or iphone classic WITH THe home button form factor while they slowly phase it out. SE Is the wildcard. It's the entry level low cost model for emerging markets. It might jack up the price too much to take it edge to edge. Or maybe an X2 mini and keep the current one in the classic line. Of all the theories this makes the most sense. I don't see any more advances or improvements to the 8. That's going to be the ultimate model in the old line.
[doublepost=1505650619][/doublepost]Actually I'm wrong. There is room for advancement on the 8. They could throw in face Id, 3d camera etc in the front bezel and call it the 9. Just with a home button and bezel.
